Stigmaeopsis (Schizotetranychus) longus
Pest description and damage Bamboo mites have a flattened body that has straw- to greenish-yellow color with small blackish green spots. Damage symptoms may look like that of a leafminer or virus infection. The mite feeding on the plant cell contents leaves a distinct damage pattern of long rectangular yellow patches visible on both sides of the leaf. Preferred bamboo hosts for this mite include the genera Sasa, Indocalamus, Phyllostachys, and Pleioblastus.
Biology and life cycle These mites form colonies on the underside of the leaves and live under a densely woven web. Generally, mites remain under the web to feed and lay eggs, but leave to defecate in black fecal piles slightly removed from the nest. Adults and nymphs sometimes are found outside the webbing, particularly as they begin to form new nests. Multiple males and females are found in the web nests, and often many webbed nests form alongside each other running down the underside of the bamboo leaves. There are many generations per year.
